Download this game and have fun.
The game contains a board with random colours. All you need to do is change the colours one at a time to have the full board of the same colour.
Well, it is quite easy and casual. What is entertaining is trying to do it in as less number of steps as possible.
For more fun, try the timed version, where you also need to complete the board in the given amount of time.
Kids would enjoy the game considering its simplicity.
